Application led April 18.

To all whom t may concern:

Be it known that I, SIEGFRIED HELD, a subject of the Emperor of Austria-Hungary, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water- Sterilizi Tanks, of which the following' is a speciV cation.

This invention relates to improvements in a tank and apparatus used for sterilizing water by means of ozone, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The primary object of the invention is to provide simple and eliicient means for thoroughly purifying or sterilizing, by f means of o zonized air, large quantities of water as the same passes from a supply pipe to a reservoirv or retaining receptacle, in which the sterilized water may be kept until it is desired for use, and from which reservoir it may be conducted by means of suitable pipes to the desired places for consump- Another object is to provide means Whereby every particle of the volume of water which passes through my improved serilizingtank'will be aerated or charged with ozonized air, to the end that sterilization of complished in the most rapid and thorough Other objectsv and advantages of the invention Will, be disclosed in the subjoined dei In the accompanying drawing, which to illustrate an embodiment of the invention-the gure is a central vertical sectional view through the tank and apparatus,

tank, which may be of any suitable size,

heads 2 and 3, is by preference. outwardly convexed, and each has a central opening.

Specification of Letters Patent.

Patented Jan. 27, 1914. 1913. serial No. 762,019.

Located in the opening of the upper head 2, 1s a pipe section 5, which extends downwardly into the tank and v has secured to 1ts lower end, by means of a screw collar 6, a screen 7, of wire cloth or other suitable material.

Connected to the u per end of the pipe 5, by means of a suitab e coupling 8, is a supply pipe 9, which leads from a source of water supply (not shown). The/opening in the lower head 3, has communication through a pipe 10, secured to said head, with a reservoir (not shown), in which the sterilized water may be 4stored for use.

Located in the lower. ortion o f the receptacle is a horizontally disposed frame, which consists of a number of beams 11, of I-beain construction, which are supported attheir outer ends by means ofbrackets 12, secured to the inner surface of the tank. Resting on the upper surface of the supporting frame comprising the I-beams 11, is anan nular trough 13, which has a centrally dis- Y `posed and upwardly extended hollow neck 14, on the upper portion of which is supported an annular flange 15, on the upper portion of another annular trough 16', the inner wall of which is upwardly tapered, -as is clearly shown. Resting on the' upper vsurface of vthe annular iange 15, is asimilar flange 17,y of another annular trough'l, which is of the same construction as the trough 16, except that it is of less diameter. An upper annular trough`19, having a central cavity or cup 20, which cu extends into the upper portion of the neck 14, rests on the upper portion of the flange 17, of the trough 18. Each of the troughs 16, 18 and 19, is provided in its lower portion witha number of openings 21, for the passage of water, and the said openings 21, in the trough 16,"ommunicate with small pipes 22, extended downwardly from the lower part of the trough 16, to near the bottomof the tro-ugh 13, and are employed for the purpose l to bepresently explained.

Extended through the upper portion of the vertical Wall ofthe tank is a pipe' 2,3, which leads from asupp'ly of ozonized air. (not shown), and has' communicating therewith within the tank a series of bra nch pipes 24, 25, and 26, which are extended downwardly within the troughs 19, 18 and 16 respectively. Each of the branch pipes'24, 25 and' 26 has communication at its lower end with and supports a tubular ring 27, which trough`13, and hasan extension 3() extended through the wall of the neck 14, and down` wardly into the trough 13, near the wall of said neck. The lower end of the branch pipe 30, communicates through suitable couplings 31, with a plurality of tubular rings 32, which are located concentrically with respect to one another within the trough 13, just y below Ithe lower ends of the tubes 22, which lead from the trough 16 into the lower part of the trough 13. Each of the tubular rings or pipes 32, is provided with numerous perforations 33, in its lower portion for the escape of ozonized air. Leading from the air supply pipe 23, is another branch pipe 34, which isextended into the coupling 8, of the water supply pipe, and has connected to its'portion within said coupling a branch pipe 35', which extends downwardly within the pipe section 5to near the lower end thereo From the foregoing and by reference to the drawing,A it will be understoodand clearly seen that by admitting' Water to the tank through the supply pipe 9, and pipe section 5, and that by opening the valve 36,

in the'air supplypipe 23, which valve con- -trols the supply of ozonizedair, whichmay l beunder pressure, water and air will be sii multaneously supplied to the tank, in Which operation iti-is' vevidentthat 'as the 'water *i passes the lower 'end of the branch pipe 35, Asuction willV be created .in said branch pipe,

causing the air to minglel with the water, which will rise in the cup 20, and

i, overflow the top of the same into the trough 19,-V from which it will pass `through t e openings 21, in the bottom thereof into the trough 18, and from thence through the openings 21, in the last named trough into the trough 16, and from thence through the openings 21, and tubes 22,@in the last named trough into the bottom trough. In its passage from the upper trough to the lower one,

' it is obvious that the ozonized airpassing from the various rings 2 7, will impregnate or aerate the wat-er, andthat further aeration will take place in the lower trough 13, by reasonof the air escaping through the perforations in the tubular rings 32, Within said trough.

It will be noted that the trough 13 has no openings in its bottom, and consequently the entire volume of water -admitted to the tank` will have to pass from the Vupper troughand from thence and the intermediate troughs into the. lower one, from which'it will overflow at its outer periphery and pass out through pipe 10, to the reservoir or storage receptacle. As the lower trough 13 has no outlet it is obvious that the water must `overiow the rim of said trough in order to pass therefrom, and as the small pipes or tubes 22 are extended from the trough 16 to near the bottom of the trough 13, it is manifest that the water passing through said tubes from the trough 16, will be discharged near the bottom of the trough 13 and in close proximity to the perforated tubular ring 32, so that the water thus discharged will be thoroughly impregnated with ozonized air or aerated.

While I-have shown my invention in its preferred form, yet it will be evident thatvarious parts canA be changed considerably from thev structure and description given without departing from the spirit of the invention, and for this reason I do not wish to be limited to the exact struct-ure shown and described.

Having thus fully described-my invention, what I claim as new and desire to secure by Letters Patent -isf- 1. The combination with a tank having an inlet for water in its upper portion and an outlet therefor in its lower part, of a plurality of, superimposed channeled members locatedin the tank and provided with means for the passage of water therefrom, and a separate perforated tubular member located in each of said channeled members and having communication with a supply of ozonizedall'.
